LUBRICATING- DEVICE.

Application led January 8, 1921. Serial No. 436,006.

To all whom t may concern.'

Be it known that I, Contr KNEBEL, a citizen of the German Empire, residing at Mannheim, Germany, have invented certain new and useful Improvements in Lubricating Devices (for which I have filed application in Germany February 23, 1916, and June 27, 1917; .also in Austria, July 23, 1918), of which the following is a specifi- 19 cation.

All lubricating devices heretofore known controlled by a ball which is immersed in the oil bath afford the inconvenience that all energy transmitted by the vibration of the l machine to the ball is consumed by the resistance of the oil. rllie higher the viscosity of the lubricant, the less reliable is the admission tothe spot to be lubricated, and inl many cases the lubrication is even entirely stopped.

The present invention overcomes this inconvenience by a ball working in a cup airtightly separated from the oil basin and further by openings, through which the lubricant is admitted or discharged, being disposed below the inferior surface of the controlling ball.

In the drawings axed to this specification and forming part thereof a device em? bodying my invention is illustrated by way of example in vertical section.

Referring to the drawings, 1 is the oil container and 2 is a cup disposed above the bottom of said container and screwed into said bottom by means of an extension 20, said container and said cup and extension beingtraversed by a vertical discharge channel 1i. 18 is a cap screwed down on the cup 2 so as to close it airtightly save for the disvcase will oil Vbe allowed to enter the charnvber to the extent of hindering the movecharge channel 17 and oil inlets 15 extending through the bottom of said cup. The upper end of the discharge channel is closed by a ball 5. Below its bottom the cup 2 carries a toothed disc 21 and a pawl 23,1ixed to a spring 22 and meshing with the teeth on said disc serves to secure said cup against angular movement. A groove in the cap 18 serves as a hold for a screw Adriver when adjusting the cap relatively tothe cup.

The inlet openings 15 are sealed by the oil in the container so that as a rule the cup and the cap screwed downv upon it form an air-tightly closed chamber. The ball 5 seated on the upper end of the discharge chani nel being displaced by the vibrations occur-l ring while the shaft to be lubricated is running, a small quantity of oil will be permitted to enter this chamber and to escape through the discharge channel, but in no.

ment-s of the ball acting as al lvalve. The stroke of this valve is controlled by the cap 18.

I claim: n

A lubricating device comprising in combination, an oil container, a chamber disposed near the bottom of said container and having an oil discharge channel extending vertically thro-ugh the bottoms of said chamy ber and said container, an oil inlet extending through the bottom of said chamber and a ball on the upper end of said vdischarge channel adapted to close said channel, said chamber being airtightly lclosed but for said discharge channel and said inlet.

In testimony whereof I aiiix my signature. v CU RT KNEBEL.
